摘要: |
On August 1, 2007, the I–35W Mississippi River Bridge (I–35W Bridge) in Minneapolis, MN, collapsed. In the tragedy, 13 people were killed and 145 were injured. (1) The National Transportation Safety Board (NTSB) turned to the Federal Highway Administration (FHWA) to provide technical expertise during their investigation. In response, NTSB issued recommendations to FHWA and the American Association of State Transportation Officials (AASHTO) to prevent similar catastrophic bridge failures. An FHWA research project to assess the performance and design of steel gusset plate connections—referred to in this report as the Gusset Plate Project—facilitated actions that addressed one of the final NTSB recommendations. The main goal of the project was to improve bridge safety by providing research and guidance on gusset plates used to connect main load carrying members. |
